Package cpace implements the CPace balanced password-authenticated key exchange, which lets two parties that share a low-entropy secret (a password) derive a strong shared key without exposing the password to offline dictionary attacks.

Package noise implements the Noise_NNpsk0_25519_ChaChaPoly_SHA256 handshake pattern from the Noise Protocol Framework (revision 34), which is all of Noise that mote needs: an ephemeral-ephemeral key agreement mixed with a pre-shared key established out of band (by the CPace exchange).
